Be 1t known that I Gon'rnmu Bucnmx'r,

a sub ect of the King of Bavaria, and re- Sldmg at Laurehutte, Germany, have mvented a new and improved Apparatus .for

Removing $uperfiuous Metal from Metal- Goated Bodies, of which the following is a specificatiou.

This invention relates to a new and improved apparatus fcr removing superfluous metal coated bodies, the inventron being particularly ads.

01 coated tubes or similar hollow ,bodies such an zinc-coated iron tubes.

Theinvention is applicable to the coating of tubes or tubelike bodies of various cross sections, which can be treated all by the same apparatus without requiring a readigetme'nt of the same.

the accompanying drawing: Figure 1 his a longitudiual SGCtlOfl of an apparatus embodyin' my invention; Fig. 2 an end view art y in section thereof; Fig; 3 a

Fig. 7 a cross section thereof, and detail of a modification of the knocking out device.

The apparatus comprises essentially a frame 1 supported on casters and cm a pair of horizontal rails 95 which at their forward end connect with a pair" of inclined rails B,"the latter being secured at their lower ends'to a bracket 2 of the frame. Above each rail pair 9, 8 extends the upper run of an endless conveyer chain 7-pass1 over dpulleys 7', 2', T and provided wi aline tappets 7, the chaixiz bein driven in suitable manner (not shown). appets 7 are adapted to removably engage a transversely disposed rod 23, from which a tong 24 is suspended sothat the tong is taken along by the chains Tong 24 is adapted to grasp the upper end of a tube or other body 5 from the interior of which the superfluous coating metal is to be removed,

a said tube being received by the tong at the t ll bottom of the inclined rails 8. Herethcre is arranged in front of the apparatus a veseel 4: containing the zinc or other coati bath, and provided with a wiper 6, throng which tube 5 drawn by the tong. Below the forward portion of: the frame, 1'. -e. be-

,entire length of inclined rails 8 pted for removthe superfluous metal from the interior" I 1 to be take; nlongby rod 28. and connected Fig. 8 a

-9, there is arranged a tray' 11 adapted to reout of the. interior of tube 5. Tray 11 is provided near its top with a plurality of spaced horizontal grate bars 10, cohstitub ing tapping devices. As tube 5 is drawn over t e tray by tong 24, its freely sus- !metal is loosened and may readily fall out of the tube into said tray.

Upen railsfl travels a carnage 17 adapted ready for the reception bf tube 5. Near the jends of rails 9,. there is provided at the side of one. of the chains 7, an inclined abutment tilted during the further advance of the chain, that it becomes dislodged from "tappets? and thus becomes released from the chain, whlllg' lcarriage 17 becomes simultaneously rel thuslibera ed willcease to exercise a p on' latfor 14, while the uncoupling of rod 23 l d-om chains 7 will cause tong 24 to release 'tube 5. The tube which had previously been laid by the tongs against platform 14 will now be swung into a horizontal position, Rod 23 will dro together with tong 2% through achute 2 upon an endless conveyer 22.- The latter runs along the side of the within reach of the starting point 6.

On that side of the machine frame oppotank 15. Within tank 15 is mounted a rotary shaft 19 provided with a lurality of rolled from the platform 14 into the tank. The tube after being properly cooled will thus' be lifted by the wings out'of the tank and thrown into a cart or other receiver.

The operation of the'machino will be ap- ,parent om the above description. After 5 by the tong24= out Patented Aug. 6 19116. i

and below portions of the horizontal-rails ceive the su rfluouscoating metal knocked pended lower end will strike the successive grate barsyso that the superfluous coatmg I forward travel of the carriage, so as to be frdm the rod.' The carria e' machine and carriesthe rod and tong back site to conveyor 22; there isarranged a water dfl'ada ed'to be engaged by red 23. When the ro strikes this abutment, it will be sowings 20, that are adapted to 1p into the tank and grasp the tube which had of the coating bath 4, it will be carried in a freely suspended state over grate 10, so as to successively strike the grate bars with its lower end. Owing to the substantial weight of the tube and to the inclined position of the latter, these'rapidly following blows will cause the surplus zinc remaining in the tube to be loosened up and to drop freely out of the same into tray 11. In this Way the interior of the tube is cleaned out in a simple manner, and waste of coating metal is avoided. The tube emptied as described is placed by tongs 24 against the platform 14,while the latter is held in an inclined p0 sition by carriage 17. VVhe'n bar 23 carrying tongs 24"strikes abutment 18 the pull on the platform ceases and the latter is swung back into a horizontal position. The tube 5 is now rolled sidewise off the platform into cooling tank 15 from which it is ultimately ejected by wings 20. I

Fig. 8 illustrates a modification of the knocking out mechanism. Here grate 10 is supplanted by a rotating shaft 13 carrying beaters 12 that are adapted to successively strike the sides of the tube to be cleaned, the latter being suspended in a vertical position. i
